Arizona Diamondbacks Insights

• Ryne Nelson – Over/Under 4.5 Strikeouts (-155/+120)
  Ryne Nelson’s slider usage has risen by 7.5% from last year to this one (12.6% to 20.1%) .
  Explain: Because sliders are one of the most effective pitches to use, a pitcher who alters his pitch mix to use more of them will often see more success as a result.
• Ildemaro Vargas – Over/Under Hits
  Ildemaro Vargas is projected to bat 2nd in the lineup in this matchup, which would be an upgrade from his 50% rate of hitting in the bottom-half of the batting order this season.
  Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
• Arizona Diamondbacks batters collectively grade out 10th- in the league for power since the start of last season when judging by their 9% Barrel%.
  Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.

Baltimore Orioles Insights

• Baltimore Orioles – 1st Five Innings (F5) Moneyline (-130)
  Trevor Rogers’s 91.6-mph fastball velocity this year grades out in the 17th percentile out of all SPs.
  Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs.
• Colton Cowser – Over/Under 0.5 Hits (-120/-110)
  The Arizona Diamondbacks don’t have any same-handed relievers in their bullpen, so Colton Cowser is certain to never face a bullpen mismatch all game.
  Explain: Hitters perform worse against pitchers of the same handedness (i.e. righty-vs-righty), and being able to avoid those matchups against the bullpen boosts performance and creates hidden edge.
• Ryan Mountcastle – Over/Under Total Bases
  Ryan Mountcastle has a 97th percentile opposite-field rate on his flyballs (38.2%) and has the good fortune of hitting them towards the game’s shallowest RF fences in today’s game.
  Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.
